安卓版Twitter无法获取访问令牌。

Question

当调用provider.RetrieveAccesstoken(comsumer, verifier)时，我会收到错误消息“服务器回复中未设置请求令牌或令牌密钥。您使用的服务提供商可能存在问题。”但奇怪的是，我只有在某些情况下才会出现此错误。起初我的代码可以正常工作并发布消息。然后第二天，当我尝试在家里的电脑上重新安装应用程序时，我遇到了这个错误。回到我的工作站后，我再次遇到了相同的错误，但在按下启动过程的按钮后，它又能够正常工作并在Twitter上发布消息。这到底是怎么回事？有人能解释一下吗？

我在Android 2.2上运行了两个模拟器，它在WQVGA400模拟器上的工作频率比WVGA800模拟器上的工作频率更高。

我还收到通知“BufferedReader构造函数中使用了默认缓冲区大小。如果需要8k字符缓冲区，则最好明确指定。”这是否与我的内存或存储令牌密钥有关？听起来像是服务繁忙无法在联系时进行回复。

代码：

为了易读性，我删除了异常和导入

public class TestAgainActivity extends Activity {

private String CONSUMER_KEY = "xxxxx";
private String CONSUMER_SECRET = "xxxxxxxxxxxx";
private String CALLBACK_URL = "myapp://twit";
private OAuthConsumer consumer; 
private OAuthProvider provider;
private String authUrl;

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    Button loginButton = new Button(this);
    loginButton = (Button)findViewById(R.id.button1);
    loginButton.setOnClickListener(login);

    consumer = new CommonsHttpOAuthConsumer(  
            CONSUMER_KEY, CONSUMER_SECRET);  

    provider = new DefaultOAuthProvider(
            "https://api.twitter.com/oauth/request_token",
            "https://api.twitter.com/oauth/access_token",  
            "https://api.twitter.com/oauth/authorize");  

}
private OnClickListener login = new OnClickListener() {
    public void onClick(View v) {
        AskOauth();
    }           

};

public void AskOauth(){

    try {

        authUrl = provider.retrieveRequestToken(consumer, CALLBACK_URL);

    Here i store the Consumer token and tokenSecret
        SharedPreferences savedTokens = getSharedPreferences("savedTokens", 0);
        SharedPreferences.Editor editor = savedTokens.edit();
        editor.putString("savedToken", consumer.getToken());
        editor.putString("savedTokenSecret", consumer.getTokenSecret());
        editor.commit();

        startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse(authUrl)));

    } catches{
}

}

@Override
protected void onResume() {
    // TODO Auto-generated method stub
    super.onResume();

    SharedPreferences savedTokens = getSharedPreferences("savedTokens", 0);
    String saved_token = savedTokens.getString("savedToken", "empty ShP");
    String saved_tokenSecret = savedTokens.getString("savedTokenSecret", "empty ShP");
    consumer.setTokenWithSecret(saved_token, saved_tokenSecret);

    System.out.println("consumer token "+consumer.getToken());
    System.out.println("consumer tokenSecret "+consumer.getTokenSecret());

Uri uri = this.getIntent().getData();  


    if (uri != null && uri.toString().startsWith(CALLBACK_URL)) {

      SharedPreferences savedTokens = getSharedPreferences("savedTokens", 0);
      String saved_token = savedTokens.getString("savedToken", "empty ShP");
  String saved_tokenSecret = savedTokens.getString("savedTokenSecret", "empty ShP");
      consumer.setTokenWithSecret(saved_token, saved_tokenSecret);

        String verifier = uri.getQueryParameter(OAuth.OAUTH_VERIFIER);  

        try {

        Here i sometime get the error! 
        provider.retrieveAccessToken(consumer, verifier);
        AccessToken accesToken = new AccessToken(consumer2.getToken(), consumer2.getTokenSecret());

        Twitter twitter = new TwitterFactory().getInstance();
        twitter.setOAuthConsumer(CONSUMER_KEY, CONSUMER_SECRET);
                twitter.setOAuthAccessToken(accesToken);
                Date d = new Date(System.currentTimeMillis());
                String tweet = "This message is tweeted " + d.toLocaleString();
                try {
                twitter.updateStatus(tweet);
            } catch (TwitterException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }      

        } catch (OAuthMessageSignerException e1) {
        }

我看到这个应用程序也允许Consumer和Provider是通用的，可以使用http进行通信。所以你可以有以下的私有成员变量：

• private OAuthProvider provider;
• private CommonsHttpOAuthConsumer consumer;
• private CommonsHttpOAuthProvider provider2;
• private OAuthConsumer consumer2;

但似乎并不重要。 - EvertvdBraak

成功了！而不是使用Oath标志库

provider.retrieveAccessToken(consumer,verifier)

我使用了Twitter4j库

getOAuthAccessToken(requestToken, verifier)

    String verifier = uri.getQueryParameter(OAuth.OAUTH_VERIFIER);
    Twitter twitter = new TwitterFactory().getInstance();
    twitter.setOAuthConsumer(CONSUMER_KEY, CONSUMER_SECRET);
    AccessToken accessToken = null;//get stored request tokens from database
    mDbHelper = DbAdapter.getInstance();
    mDbHelper.open();
    String[] dbRequestTokens = mDbHelper.getTwitterRequestTokens();
    mDbHelper.close();
    RequestToken requestToken = new RequestToken(dbRequestTokens[0], dbRequestTokens[1]);
    try {
        accessToken = twitter.getOAuthAccessToken(requestToken, verifier);
        //dataBase store accessTokens to tweet message  or acces other twitter recources, and don't forget to set the OAuth Consumer with consumer key and secret
        mDbHelper.open();
        mDbHelper.setTwitterAccessTokens(accessToken.getToken(), accessToken.getTokenSecret());
        mDbHelper.close();
        return "logged in succesfully";
        } catch (TwitterException e) {
        e.printStackTrace();
        return e.getMessage();
    }
